Overview
This protocol describes an organotypic slice assay optimized for the postnatal brain and high-resolution time-lapse imaging of neuroblast migration in the rostral migratory stream. The method allows for the visualization of migrating neuroblasts in the postnatal brain through tissue cross transplantation between organotypic mouse brain slices.
